To demonstrate ultrasound contrast agents to be important potentiators of high-intensity focused ultrasound (HIFU), we prospectively assessed the effectiveness of HIFU combined with nanoscale ultrasound contrast agents for the treatment of breast VX2 tumors in rabbits. We found that the change of grayscale value in the target area in the HIFU+nanobubble group was significantly higher than that in...
The purpose of the present study is to prepare a nanoscale ultrasound contrast agent and to investigate its characterization and ultrasonic imaging in vivo.Nanoscale ultrasound contrast agent was prepared by machine vibration and low speed centrifugation, and the appearance, distribution, diameter, and zeta potential of the nanoscale ultrasound contrast agent were measured. Contrast-enhanced ultrasonography...
